摘要

Abstract

Seasonal variations of water masses in the East China Sea (ECS) and adjacent areas are investigated

based on historical data of temperature and salinity (T-S). Dynamic and thermodynamic mechanisms that affect seasonal variations of some dominant water masses are discussed

with reference to meteorological data. In the ECS above depth 600 m

there are eight water masses in summer but only five in winter. Among these

Kuroshio Surface Water (KSW)

Kuroshio Intermediate Water (KIW)

ECS Surface Water (ECSSW)

Continental Coastal Water (CCW)

and Yellow Sea Surface Water (YSSW) exist throughout the year. Kuroshio Subsurface Water (KSSW)

ECS Deep Water (ECSDW)

and Yellow Sea Bottom Water (YSBW) are all seasonal water masses

occurring from May through October. The CCW

ECSSW and KSW all have significant seasonal variations

both in their horizontal and vertical extents and their T-S properties. Wind stress

the Kuroshio and its branch currents

and coastal currents are dynamic factors for seasonal variation in spatial extent of the CCW

KSW

and ECSSW

whereas sea surface heat and freshwater fluxes are thermodynamic factors for seasonal variations of T-S properties and thickness of these water masses. In addition

the CCW is affected by river runoff and ECSSW by the CCW and KSW.
